PILE

Application led March 17, 1928.

My present invention relates to pile wires, and has particular reference to that type of pile wire which is provided with means for detachably receiving and holding a cutting blade,

One of the objects of the invention is the production of a pile wire of this character by means of a method which is not only extremely etiicient in producing a staunch tin ished article, but which is of such extreme simplicity that the time and cost of manufacture is substantially reduced. Accordingly, a feature of the invention lies in shaping and manipulating the pile wire itself for the purpose of producing the desired result.

The blade holding portion of the pile wire made in accordance with my invention is provided with a blade receiving channel having one of its walls extended beyond the other to form the usual spoon or had with anchoring means in the holder for locking the blade in the channel and one of the features of my invention resides in the manner in which the spoon or head of the blade is formed. This is herein disclosed as involv ing a distortion of one end of the pile wire so as to provide a spoon or head portion which is to one side of the longitudinal axis thereof so as to have this spoon clear the channel in which the blade is to be received and preferably to have this spoon form a continuation of one wall thereof.

In the preferred method of carrying ont my invention the distortion ot' the end of the pile wire is effected by a rolling process.

Another feature of my invention is the manner in which the blade receiving channel is formed in the pile wire and the relationship which such manner of formation bears to the manner in which the spoon is formed.

For the attainment of the foregoing objects and such other objects as may hereinafter appear or be pointed out. I have illustrated one embodiment of my invention in the accompanying drawings, in which Fig. l is a perspective view of an end portion of a pile wire prior to any manipulation or shaping thereof;

Fig. l after the end portion has been distorted;

Figs. a and 5 are views similar to Figs. 2. and 3 respectively after the channel has been formed;

G is a cross-sectional elevational view taken aiong the line G-G of Fig. 5 showing in dotted lines the position which a blade will assume within the slot, and showing a preferred construction suitable for holding the blade in position;

Fig. i' is a fragmentary plan view, showingthe rear portion of the slot illustrated in Fig. 6; and

l? 8 is a fragmentary elevational View showing a modification.

its my invention is particularly intended for and is therein disclosed as embodying` the blade holder and forming it from the end of a pile wire; I have illustrated in perspective in Fig. l an end 10 of the pile wire from which such holder is formed as will shortly be described. rEhe pile wire illustrated is of the conventional character employed and which is in the form of an elongated flattened bar of metal having the parallel side faces lO and ll, and the parallel top and bottom faces 12 and 13 respectively, the latter being much narrower than the side faces as shown.

By exerting pressure to what may be termed the forward portion of the Wire in i a direction perpendicular to the side faces Al() and lll, the forward portion of the wire is distorted so as to flatten and expand this end to thereby provide a head or spoon portion llt which is not only wider than the side faces 10 or ll but which is considerably elongated in accordance with the predetermined reipiirements Preferably, this distortion is effected by a. rolling process. but. it will be understood that any other process may be employed.. The compression or attenuatiou is preferably such that the final thickness of the head or spoon portion is substantially less than one-half of the original thickness between the faces 10 and w1l for reasons that will shortly be understood. This is clearly shown in Fig. 3. Moreover, the head is preferably constructed so th:v i e rear face l5 is substantially flush with the face 11 while its front face is substantially parallel. ther-eter Fer' vvbieh scribed and illustrated for the purpose of explaining the nature ot niy invention may ie made by those skilled in the art without departing rom the spirit and scope of the invention as expn ssed in the appended claims. lt is therefore intended that these. claims be interpreted as illustrative rnd not in a limiting sense.

lVhile I have illustrated and described my blade holder as niade troni and integral with the pile Wire, lVet it will be understood that as far as some phases of my invention are concerned, this is not essential.

Having thus described my invent-ion and illustrated its use, what l claim as new and desire to secure by Letters ljatent is:

l. The method of making a blade holder adapted to 'torni part o'l a pile wire, which con prises compressing an end portion ot a bar in the direction ot its Width so as to provide a flattened head portion of increased area With respectv to that ot the portion which has been compr ed.

2. The method` of limiting a blade holder 'for a pile wire, which comprare atteniiating an end ot a bar to torni a head, and forming a blade holding slot in the bar adjacent and open to said head and disposed along a plane entirely to one side ot said head.

The method of making a blade holder adapted to forni part ot' a pile Wire, which comprises flattening an end ot a bar to torni a head having a thickness less than that of the bar, and slitting the bar adjacent to the head to forni a blade holding channel open to the head and having Walls of which one is an integral continuation ot' said head.

fl. The method of making a blade holder tor a pile Wire, which comprises compressing an end ot a bar to torni a iiattened head ot' a thickness substantially half ot that of the bar, and slitting the bar adjacent to the head to torni a channel which is so positioned as to receive a substantially tlat blade lying in a plane substantially parallel to the head said channel being open to and entirely on one side thereof.

5. The method of making a pile Wire. which comprises flattening anend thereoil to forni a head, and forming a longitudinal slot in the Wire adjacent and open to said head and otl'set with respectthereto, whereby a blade may be inserted into said slot with its tornai-d end disposed entirely to one side of said head.

G. The method ot' making a pile Wire having a blade holding portion, which comprises distorting an end ot' the Wirel to forni a heath torniing a longitudinal channel in the wit e adjacent to the head and otlset With respect thereto, said channel being adapted to receive a fiat blade, and striking up a portion ot the head toward the plane ot the channel to provide a tab adapted to engage the trent edge ot' the blade.

In witness whereof, I have signed this specification this 11th day ot March, 1926.
